SPINDLE Specification of Letters Patent.

Patented sept. 24,1907.

' plieatiou tiled August 21,1906. Serial No. 331,484.

To all whom 'it may concern.:

. Be it known that l, E DWARD TACHE, a subject of the King of Great Britain and Ireland, residing at New Marketrsin the countyoi Rockingham, State of New Hampshire, have invented certain new and use- ;ul Improvements in Spindles, of which the following is a description, reference being hadlto the accompanyingdrawlings, forming a part hereof?.

'l The object of the present invention is to produce an improved self-lubricating spindle for 'spinning machines, andA it consists in the improved spindle de scribed in the following specification andclaimed in The figure represents a vertical` central seetion'oi my improved spindle. y

1 is a bolster-case threaded as shown and provided with a nut 2, whereby it may be se'cured to a spindle rail not shown. This'loolster case will contain a considerable quantity of oilwhen the spindle 'is in operation.` p.

3 is a bolster threaded as shown at 4 and provided with a lock nut 5, whereby the bolster is adjust-ably secured in the bolster case.` Said bolster is provided with perforations 6-6 through which oil contained in ther'bolster case has access to the spindle bearings.

7 is a step or bearing carried by the `holster 3 as shown, said bearing being' screw-threaded and engaging corresponding threads in the bolster. v

d is the spindle. This spindle is provided with al conical end as at 9 adapted to rest withinn corresponding depression in the step 7. and thereby form a conical bearing for the lower end oi theA spindle.

10 is a shoulder formed upon the spindle; undsaid spindle is flared or tapered ut l1 shown.

12 is an upper bearing for the spindle, and comprises a depending portion .i3 against which tho shoulder l0 bears and is provided with an oil groove i4 and openings 15 through `which oil reaches the bearing. lo' is a.

passage leading from seidV oil groove to the. oil space within the bolster. The holster is recessed as at i7; and it Will be seen that as the spindle rotates centrifugal force will causethe oil contained in tho holster euse.

and which has access to the spindle through the opel 18 is a sleeve whirl by which the spindle is operated. It will thus be seen that the lower spindle bearing is submerged in oil contained in the bolster case, and that a continuous, flow of oil is supplied to tle upper bearing, thereby keeping it in-a flooded condition.

Having thus described my invention and explained the inode of operation thereof, I claim and desire to secure by Letters Patent: i

1. ln :l spindle, u bolster ense adopted to contuln oil und having un interiorly threaded portion adjacent lts upper end; means whereby said ease may he secured to a spindle ruil; a holster threaded exteriorly at its upper cud to engage the threaded portion ol' said bolster case; :i lock nul. for securing snid purts after they have been prlniorly adjusted; upper und lower' bearings carried by said bolster; a spindle supported in said hearings; u shoulder upon sind spindle in contact with Suid upper lle-.iring, whereby upward movement of the spindle is prevented; suid spindle huvinpy un upwurdl'y Ilured portion termino-ting :it the snid shoulder; and openings in suid holsteithrough which oil routuned 1n the hols-ler euse hns :recess to the spindle. i
